ASTM A53 G.Bndi imodzi mwamiyezo yachitsulo yachitsulo yopangidwa ndi American Society for Testing and Materials (ASTM). Zotsatirazi ndikuyambitsa mwatsatanetsatane kwa chitoliro chachitsulo cha A53 Gr.B:
1. Mwachidule
ASTM A53 Gr.B chitoliro chachitsulo chosasunthika. Pakati pazitsulo zazitsulo zazitsulo zopangidwa ndi American Society for Testing and Materials (ASTM), ASTM A53 imagawidwa m'magulu awiri, A ndi B. ASTM amaimira miyezo ya ku America. Chikhalidwe chofanana cha Chitchaina cha A53A ndi GB8163, chomwe chimapangidwa ndi No. Amagwiritsidwa ntchito kwambiri popanga mapaipi azinthu.
2. Njira yopanga
ASTM A53 G.Bmakamaka amagwiritsa ntchito ukadaulo wa chitoliro wopanda msoko popanga. Tekinoloje ya chitoliro yopanda msoko imatanthawuza njira yosinthira billet kukhala chitoliro chachitsulo chokhala ndi makulidwe a khoma lofanana ndi malo osalala amkati ndi akunja kudzera munjira monga kuphulika kwa billet, kugudubuza, ndi kukulitsa m'mimba mwake. Ngakhale muyezo ASTM A53 amalola ntchito luso welded chitoliro kupanga mipope zitsulo, popangaASTM A53 G.B, ukadaulo wa chitoliro wopanda msoko ndiye njira yayikulu yopanga.
3. Zogulitsa Zamalonda
Makulidwe apamwamba a khoma ndi m'mimba mwake m'mimba mwake: Makulidwe a khoma ndi m'mimba mwake akunja a ASTM A53 Gr.B chitoliro chosasunthika chimakhala cholondola kwambiri ndipo chimatha kukwaniritsa zosowa zamitundu yosiyanasiyana yovuta.
Kukana kwamphamvu kwamphamvu komanso kukana dzimbiri:ASTM A53 G.BChitoliro chosasunthika chimakhala ndi kukana kuthamanga kwambiri komanso kukana kwa dzimbiri, ndipo imatha kugwira ntchito mokhazikika kwa nthawi yayitali m'malo ovuta.
Ntchito Yonse: Chitoliro chosasunthika cha ASTM A53 Gr.B ndi choyenera pamapaipi otumizira gasi, madzi ndi madzi ena, kuphatikiza kugwiritsa ntchito mafakitale, makina operekera madzi ndi kutentha.
4. Standard range
Muyezo wa ASTM A53 GRB umagwira ntchito pa msoko wowongoka (wowotcherera) ndi mapaipi achitsulo osasunthika, ophimba ma diameter osiyanasiyana akunja, makulidwe a khoma ndi njira zopangira. Malinga ndi zofunikira zosiyanasiyana zogwiritsira ntchito, mapaipi a ASTM A53 GRB amathanso kukhala malata, kukhala mizere, yokutidwa, ndi zina zotero kuti apititse patsogolo kukana kwa dzimbiri ndi moyo wautumiki.
